Peds DM2 Flashcards
Name 4 typical symptoms of DM2
- slow and insidious onset
- most common in overweight patients from a minority group (Native American, blacks, Pacific Islanders)
- signs of insulin resistance
- strong family history
Physical findings of DM2
obesity acanthosis nigrans PCOS HTN retinopathy
When to consider testing
Overweight and 2/3 of the following
- family history in 1st or 2nd degree relative
- minority race
- signs of insulin resistance (acanthosis nigrans, HTN, dyslipidemia, PCOS)
What labs other than BG suggest DM2?
- elevated fasting C-peptide
- elevated fasting insulin
- absence of autoimmune markers (glutamic decarboxylase and islet cell antibodies)
Name 3 urine tests for albuminuria.
- random spot albumin-creatinine ratio
- 24 hour collection for albumin and creatinine, alson allows for simultaneous creatinine clearance
- timed (4-hour or overnight) collection
When should you test for lipids?
after stable glycemia is achieved and every 2 years if normal
Lipid level goals (TG, LDL, HDL)
TG <150
LDL <100
HDL >35
What is the fasting glucose goal?
less than 126
What is the HbA1c goal?
less than 7%
What are the advantages of HbA1c over BG?
- it captures long-term exposure
- it has less biologic variability
- it does not require fasting or timed samples
- it is currently used to guide management decisions
What should you check annually?
microalbuminuria and dilated eye exam
Name 4 acute complications of DM2.
hyperglycemia
hyperglycemic-hyperosmolar state
DKA
hypoglycemia
Name 3 complications from insulin resistance
HTN
dyslipidemia
PCOS
Name 4 long-term complications of DM2
- nephropathy
- neuropathy
- retinopathy
- coronary artery disease
T/F
Adults diagnosed with DM2 before age 45 have a higher risk of cardiovascular disease.
True- early onset DM2 appears to be more aggressive from a cardiovascular standpoint
What does basal insulin do?
suppresses lipolysis, proteolysis, and glycogenolysis
What dose first-phase insulin secretion do?
facilitates the peripheral use of prandial nutrient load, suppresses hepatic glucose production, and limits postprandial glucose elevations
What does the second phase of insulin secretion do?
follows the first-phase and is sustained until normoglycemia is restored
Which phase of insulin secretion is most reduced in early stages of DM2?
first phase
What is the basis for the progression from impaired glucose tolerance to DM2?
failure of the beta cells to keep up with the peripheral insulin resistance
Name 7 risk factors for DM2 in young persons
- obesity and inactivity
- minority race
- family history (1st & 2nd)
- age 12-16 (puberty)
- low or high birth weight
- maternal DM or gestational
- not breastfed
T/F
antipsychotic medications increases the risk for developing DM2
True
Is the prevalence of DM2 higher in boys or girls?
Girls
After 30 years of postpubertal DM, how many develop nephropathy?
44% with DM2
20% DM1
T/F
Times of acute crisis or complications are a good time to reinforce the importance of self management
True
How do children present differently with DM1?
- occurs in all races
- onset is acute and severe
- thin
- no signs of insulin resistance
How is overweight/ obese defined?
- Above or equal to 85th percentile BMI
- Weight at 85th %
- Weight 120% of ideal for height
What is the prevalence of acanthosis nigrans?
90%
What are the characteristics of PCOS?
hyperandrogenism and chronic anovulation
When should screening begin?
At age 10 or when puberty starts (if younger)
